Gary,
Thanks for the reply!  I have no intention of introducing any electric to my radio until I recap it.  I just wanted to pick a place to start, and I figured the cord was a good starting place.  My thoughts of a 3 wire were to have a ground on the chassis, but if that is not needed then I would still like to use a polarized 2-prong.  Still, I am confused how to choose which side of the terminal is the neutral and which is the load.  How does one distinguish from the schematic which is which?  I've read that the neutral often is on the switch side of these, but I am not sure.  I would like to learn how to decipher this from the schematic for future knowledge if anyone can help.
